ABSTRACT

0070444
Yoo

The PI proposes to investigate a wavelength interchanging cross-connect geared towards applications in the Next Generation Networks. In particular, he will pursue a parametric wavelength interchanging cross-connect incorporating difference-frequency wavelength converters with integrated pump sources. The resulting wavelength interchanging cross-connect has the following unique properties:


accommodates signals of any protocol and format,
crossconnects subcarrier multiplexed optical header and baseband data payload,
offers scalability of Benes architecture,
utilizes multichannel wavelength conversion for reduced architecture,
achieves polarization insensitivity and wavelength independent filtering.

The proposed effort makes comprehensive studies of the Wavelength Interchanging Cross-Connect covering architecture, simulation, design, fabrication and systems integration issues. Specifically, he will pursue an integrated effort of the following research activities:

1. Wavelength Interchanging Cross-connect Architecture Studies, which will pursue a transparent and scalable architecture suited for Next Generation Network applications,
2. Wavelength Conversion Technology Studies, which will design, fabricate, and prototype wavelength converters supporting transparent multichannel wavelength conversion, and
3. Cross-connect Integration, which will bring space switches and wavelength converters together to form a wavelength interchanging cross-connect. The designed architecture and network elements will be put to test at this step and the simulation results will be experimentally verified.
